To all wwm it may concern.-

Be it known that I, GEORGE S. CHASE, of Cambridge, in the county of Middlesex and State of Massachusetts, a citizen of the United States, have invented a new and useful Imn provenient in Metal Door-Mats, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification, in explaining its nature.

The invention relates to a metal door-mat having a Inet-al rim and parallel twisted flat metal strips placed any desired distance apart and united at their ends to the end bars of the rim and stayed to the side bars when desii-ed.

In the drawings, Figure l is a plan View of my invention. Fig. 2 is a part of strip and frame, showing one way of fastening. Figs. 3 and 3 illustrate a modification hereinafter described. Figa is a sectional view of one of the strips before being twisted to take its place in the frame of the mat.

A represents the metal rim. It may be of any shape in section, and is preferably in one i piece, having its ends united by welding or riveting.

B represents the parallel twisted flat metal strips. Each strip is made from a dat blank of substantially the shape represented in Fig. et by twisting or turning to any desired eX- tent, and the ends b of each twisted strip are secured to the side barsa of the metal rim by riveting. as represented in Fig. l, or as represented in Fig. 3, or in any other Way. These are secured to the rim, preferably, to bring the edge of each strip slightly above the up per level of the rim. W'here the inat is of some width, the strips are stayed to each other and to the side by the stay or cross pieces c.

vIn Figs. 3 and 3 I have represented the twisted at strips as extended crosswise and secured to two bars a', which taire the place of the riin above referred to, and the ends of the twisted strips are made very flat and bent to forin eyes d, which embrace the bars a', and the strips are separated from each other by spacing-washers e.

The advantage of the invention arises from its effectiveness and the cheapness of its construction. In the small sizes it is useful npon steps as a niat or tread.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States As an improved article of manufacture, a inetal door mator tread having supportinghars, and the parallel twisted flat metal strips B, united at their ends to the said bars, as and for the purposes described.

GEORGE S. CHASE.
